Solar module and solar module manufacturing method

A solar module comprising:

• a plurality of solar cells;
• wiring members electrically connecting the plurality of solar cells;
• and
• a resin adhesive layer bonding the solar cell and the wiring member;
• the wiring member having a first wiring member piece connected electrically to one solar cell of two adjacent solar cells, and a second wiring piece connected electrically to the other solar cell of the two adjacent solar cells and connected electrically to the first wiring member piece;
• and
• the tip portion of the second wiring member piece is interposed between the first wiring member piece and the one solar cell of the two adjacent solar cells.

A method for manufacturing a solar module comprising the steps of:

• preparing a plurality of solar cells having a first electrode and a second electrode on one main surface;
• preparing a first wiring member having a first insulating film having flexible properties, and first wiring arranged on one main surface of the first insulating film;
• creating a solar cell string having a plurality of electrically connected solar cells by bonding the solar cell to the first wiring member using a resin adhesive while the first wiring side of the first wiring member is facing the solar cell to establish an electrical connection;
• inspecting the solar cell string for the presence of any defective solar cell, disconnecting the first wiring members bonding a defective solar cell to the solar cells adjacent to the defective solar cell, and removing the defective solar cell from the solar cell string when a defective solar cell has been discovered;
• and
• electrically connecting a new solar cell to the solar cells adjacent to the defective solar cell using new wiring members, the disconnected pieces of the first wiring members being bent to form first exposed portions in the disconnected pieces having first wirings exposed on the one main surface side of the solar cell, and the new wiring members being connected electrically to sections of the first wirings positioned in the first exposed portions.

A solar module comprising:

• a solar cell;
• a wiring member having resin film and wiring arranged on the resin film;
• and
• solder electrically connecting the solar cell and the wiring member either directly or indirectly;
• the resin film not being provided in at least some of the section of the wiring member electrically connected to the solar cell either directly or indirectly.
